On average, public debt rose from 60% of GDP on the eve of the crisis (end-2007) to almost 75% by end-2009. IMF country teams project debt ratios to continue rising over the next five years, averaging more than 85% of GDP by 2015. Japanâs public debt is expected to reach nearly 200% of GDP in 2010.
Ependymal Cells [edit]. The ependyma is made up of ependymal cells, ependymocytes, a type of glial cell. These cells line the CSF-filled ventricles in the brain and the central canal of the spinal cord. The cells are ciliated simple columnar epithelium-like cells.heir apical surfaces are also covered with microvilli, which absorb CSF. Ependymal cells also produce CSF. Within the ventricles of the brain, a population of modified ependymal cells and capillaries together form a system called the choroid plexus, which produces the CSF.
Summary. The posterior horn of the lateral ventricle in the monkey brain varies in size in different individuals. In this part of the ventricle, the ependymal cells bear cilia, microvilli, microblebs and supraependymal, axon-like cell processes.
